Lionel Messi marked his record sixth World Cup appearance with a memorable hat-trick as defending champions Argentina opened their campaign with a commanding 3-0 victory over Algeria in Kansas City on Tuesday.

The prolific forward, who recently returned from a minor hamstring injury, showcased his enduring brilliance by netting three goals in the opening match of the 2026 FIFA World Cup. This performance not only secured a vital win for Argentina but also saw Messi achieve a personal milestone, becoming the joint-highest scorer in World Cup history.

Messi's first goal, initially disallowed for offside in the eighth minute, was quickly followed by a trademark mazy run and a powerful strike from the edge of the box that beat Algeria's goalkeeper, Luca Zidane. He extended Argentina's lead on the hour mark with a simple tap-in from a rebound, and completed his hat-trick in the 76th minute with another low drive from outside the area. This final goal drew him level with former Germany striker Miroslav Klose on 16 World Cup goals.

The victory sets a positive tone for Argentina's defense of their title, as they aim to become only the third nation to successfully retain the World Cup. Messi's impressive display, despite a recent injury scare, suggests he is in prime form to lead his side's challenge. The forward was substituted three minutes after his final goal to a standing ovation, appearing to indicate he was being rested for future matches.

Algeria, the reigning Africa Cup of Nations champions, struggled to make an impact offensively, though they too had an early goal disallowed for offside. Their performance offered little threat to the reigning champions, who were determined to avoid an opening-game upset, a fate they suffered in the Qatar 2022 tournament before going on to win the final.

Messi's journey to this record-breaking appearance has been remarkable. Having spent the majority of his club career with Barcelona before a stint at Paris Saint-Germain, the eight-time Ballon d’Or winner now plays for Inter Miami in Major League Soccer. His return to form was evident in a recent tune-up match against Iceland, where he scored after playing just 20 minutes.

This match also marked Messi's 200th international appearance for Argentina, a testament to his longevity and consistent impact on the global stage. His performance against Algeria underscores his continued influence and his ambition to add another World Cup title to his illustrious career.

The focus now shifts to Argentina's next fixture as they navigate their path through the tournament. Messi's current form and the team's strong opening performance position them as serious contenders to repeat their championship success.
